ABSTRACT:
Inbound and outbound parallel conveyors carry parts supported on a screen tray engaged by the conveyors. The parts are conveyed to a station on the inbound conveyor line where a substance is applied to a first portion of the parts. The parts are then conveyed to an inverting apparatus which inverts the parts onto another tray screen so that the relative locations of the parts on the tray screen are maintained to prevent masking each other when the substance is applied to a second portion of the parts. The parts are then conveyed to another location where the upwardly disposed second portions of the parts receive a coating of the substance. The inverting operation is accomplished by the inverting apparatus, slideably engaged to a lateral mobile assembly, which engages the parts tray from the conveyor within a lower tray receptacle. The parts are clamped between the lower tray and an upper screen tray removably engaged in an upper tray receptacle. In order to fix the locations of differently sized parts on the tray during rotation and movement of the carrier frame, during the clamping operation, a compliant material such as vertical bristles, disposed above and below the tray screens, is displaced through the screen holes to engage the parts thereabout.
